SAFETY OIL-CAN.

Specification of Letters Patent.

Application filed June 16, 1913. Serial No. 773,833.

securely regardless of the position of the can, unless it is opened intentionally.

My invention has for its further ob ect: to provide means to securely protect the mechanism from accidental displacement, and to provide a device which will be so. constructed that the operation of "filling will automatically hold the can open, while the removal'of the funnel utilized for filling the can will permit the mechanism to automatically close the can.

My means of accomplishing the foregoing may be more readily understood by having reference to the accompanying drawings, whichare hereunto annexed and are a part of this specification, in which:

Figure 1 is an elevation, partly in section, of a can provided with my improvement. Fig. 2 is a fragmentary detail View showing the position'of the parts when the can'is being filled. F ig. 3 is a cross section taken on line w-w in Fig. 1.

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawings, 1 is the can which is provided with a nozzle 2. This nozzle has a spout 3 in which is located a wlre gauze 4 to preventthe accidental ingress of flame. The nozzle 2 is provided with an upwardly extending passage 5, to which is fitted a cap 6. This cap is provided wlth a rearwardly extendingportion 7, which is adapted to be engaged by the forward end 8 of the operating lever 9, the latter bemg pivoted upon a pin or pivot 10. This lever is formed, as better seen in Fig.3, of a U- shaped piece of metal, the upper ends 11 of which extend between the downwardly d epending sides 13 of a fixed handle'12, in which the pin or pivot 10 is mounted, these sides forming a guard to protect the operating mechanlsm of the device from accidental displacement.

The valve 14, which opens inwardly to permit the discharge of the contained'liquid,

mally in a closedposition by means of a coil sprlng 15, which engages the valve stem 16, the upper end of the latter being engaged by the forwardend 8 of the operating lever 9. I provide a guide and bearing for the valve stem 16, which as shown in the drawings comprises an inwardly projecting lug 23 wh ch is provided with a central opening in which the valve stem slides, and an annular recess in which the coil spring 15 is mounted. A washer 25 being secured to the valve stem 16 is engaged by the upper end of the 00-11 sprlng 15, which thus operates to hold the valve 14.to its seat. I 1

A tube 17 is provided to relieve the can from undue pressure, caused by expansion of its contents. Its upper end is normally closed by a valve 18, held in position by a spring 19. The outer end of its valve stem 20 passes through the lever 9 and is'provided with a nut or cap 22, which engages the lower wall of the operating lever 9, so that the movement of the latter serves to move the valve 18 from its seat.

While it will be apparent that any excess of pressure will serve to dislodge the valve 18 from its seat andthus relieve the pressure in the interior of the can, this same pressure will operate to seat the valvel l more tightly, so that any leakage therefrom is eliminated. The operation of the device is as follows: The operator desiring to fill the can grasps the handle 12 and his fingers engage the operating lever 9, when by closing the hand the parts assume the position shown in Fig. 2. The cap 6 is then raised to the position shown in the said figure and the funnel 21 is inserted. This preventsthe cap being returned to its normal position with theaccompanying result that the end 8 of. the lever 9 holds the valve '14; in an open posi-.

tion, while the same movement serves to unseat the valve 18, permitting the air to escape freely while the can is being filled.

It will be apparent to persons skilled in i the art that as soon as the funnel is removed that the spring will instantly operate to return the operating lever and the valves to their normal positions, as shown in Fig. 1,

thus effectually protecting the contents of the can from accidental contact with fire or flames.

It will be apparent from the foregoing that the pressure of the lever upon the rearand'also the filling of the can, is held nor- I wardly projecting portion 7 of the cap 6 would serve to dislodge the funnel from 1ts vertical osition. I revent this by the provision lugs 25, w ich project outwardly 5 from the downwardly projecting stem 23, which is provided as a guide and bearing for the valve stem 16. These lugs serve to prevent the displacement of the funnel-by the pressure exerted by the cap 6, so that it remains in the position hown in Fig. 2 during the operation of filling the can, which it will beobserved is directly over the opening 24, which is closed by the valve 14.

It will be observed that this construction prevents the operating mechanism from coming in contact with the lip uid, and also effectually guards the liquid rom any dirt or dust, which might accumulate on the moving parts.

Havlng described my invention, what I regard as new and desire to secure by Letters Patent is;

1. The combination with a can having a fixed handle provided with downwardly extending sides, of a nozzle secured to said I can, a spout on said nozzle, there being an i upwardly extending opening in said nozzle, 1

' a cap closing saidopening, said cap having a rearwardly extending portion, a valve which closes an opening into the can, a stem for said valve, a coil spring to hold said valve in a closed position, a lever pivotally mounted between the sides of the handle, its

forward end being adapted to engage the upper end of the said valve stem and the rearwardly extending portion of the cap, a

relief valve secured to the lever, whereby the movement of the lever serves to open the relief valve.

2. The combination with a can having a fixed handle provided with downwardly extending sides, of a nozzle secured to said can, a spout on said nozzle, there being an upwardly extending opening in said nozzle,

a cap closing said opening, said cap having.

a rearwardly extending portion, a valve which closes an opening into the can, a stem for said valve, a coil spring to hold said valve in a closed position, a lever pivotally' mounted between the sides of the handle, its forward end being adapted to engage the q, upper end of the said valve stem and the rearwardly extending portion of the cap, a relief valve held normally in a closed position, but free to open to relieve an excess of pressure within the can, the stem of said relief valve being secured to the lever, whereby the movement of the lever serves to'open the relief valve.

3. The combination with a can, of a spout secured thereto, there being an upwardly extending opening in said nozzle, a cap for said opening, spring actuated means to hold said cap normally in a closed position, there being an opening into said can, a valve c'losing said opening, an inwardly projecting lug cast or formed on said nozzle, having'a central opening in which the stem of said valve slides, there being an annular recess within said lug, a coil spring located in said recess, means to cause said spring "to hold said valve normally in a closed position, a pivoted lever to actuate said valve, a relief valve free to open .to relieve an excess of pressure Within the can, the stem of said re lief valve being secured to the said lever, means to protect the operative mechanism from accidental operation. 7

4. The combination with a can having a fixed handle provided with downwardly .extending sides, of a nozzle secured to said can,'a spout on said nozzle, there being an upwardly extending opening in said nozzle, a cap closing said opening, said cap having a rearwardly extending portion, a valve which closes an opening into the can, a stem for said valve, a coil spring to hold said valve in a closed position, a lever pivotally mounted between the sides of the handle, its forward end being adapted to engage the upper end bf the said valve stem and the rearwardly extending portion of the cap, a relief valve which closes an opening into the can, a stem for said valve, a coil spring which engages said stem to hold the valve normally in a closed position, there being an opening in the said lever adjacent said relief valve stem through which the said stem passes, and a nut secured to the end of said valve stem, for the purpose set forth sub stantially as described.

In witness whereof I have signed the foregoing specification.
